8 Claims

1. A heat exchanger comprising:

a heating body constituted by a plurality of circulation plates which are fitted into one another and between which there are formed spaces configured to be traversed by a fluid;

the heating body comprising at least one header which connects the spaces;

a manifold by which the at least one header is connected to a circuit external to the heat exchanger;

wherein the at least one header has a header cross section, the manifold has a manifold cross section which is different from the header cross section;

an adapter which is interposed between the at least one header and the manifold and which joins the header cross section to the manifold cross section;

wherein the heating body comprises a first end plate, the adapter being an independent, single-piece part having a first end directly secured to the first end plate and a second end directly secured to the manifold; and

wherein the adapter comprises at least one integrally formed bearing stop which protrudes from an outside wall of the adapter such that the bearing stop surrounds the outside wall of the adapter, the bearing stop configured to bear against the first end plate such that the bearing stop limits insertion of the adapter into the first end plate by contacting an outside surface of the first end plate.
